IMPROVEMENT IN BRONZING-MACHINES.

Specification forming part of Letters Patent N0. 130,475, dated August 13,1872. a

indicating the plane of section. Fig. 2 is a plan or top view of the same.

Similar letters indicate corresponding parts. This invention consists in combining with an endless carrying-apron a bronze-reservoir, a bronze-supply, and a bronze distributing roller, and also a polishing-roller and a cleaning-brush in such a manner that a sheet of paper or other material placed on the apron is brought in successive contact with the bronze-distributin g roller, then with the polishin g-roller, and, finally, with the cleaning-brush; and by these means the bronze applied to the paper by the distributingroller is polished, and then the surplus bronze is removed. With said endless carrying-apron is also combined a secondary cleaning-brush to free said apron from any particles of bronze which may have adhered to it. 7

In the drawing, the letter A designates a frame, which may be made of cast-iron or any other suitable material, and which forms the bearings for the working parts of my machine. In this frame are secured two rollers or drums, B B, round which is stretched an endless apron, 0. Above this apron are three rollers, D E F, the upper surface of said apron being held in contact with said rollers by three supportingrollers, G H I, situated beneath the upper portion of the apron, and forced upward by means of springs a,which act on their bearings, (see Fig. 1,) and which also render the supportingrollers yielding, so that articles of ditterent thickness can be passed through my machine. The roller D is the bronze-distributing roller. It is supplied with bronze from a reservoir, J, by means of a roller, K, which extends into the reservoir and runs in contact with the dis- F with bristles of wool, hair, or other material.

If a sheet of paper is placed on the apron, which may be provided with stops to bear against the edge of the sheet and compel it to travel forward with the apron, a certain quantity of bronze is transferred to the paper by means of the distributing-roller 5 those parts of the paper to which the bronze is to adhere being previously moistened with ink, size, or other suitable liquids. As the paper advances the bronze spread on its surface is exposed to the action of the polishing-roller E, and, finally, the brush F removes the surplus bronze,

leaving those parts of the paper which have been previously moistened covered with a coat of polished bronze.

When I use my bronzing-machine for cards or other small articles I apply a feed-table, L, at the receiving end, and an inclined board, M, at the discharge end, the latter serving to conduct the bronzed cards into the drawer N. I also use tapes, d d, stretched over the roller D and an additional roller, Q, to prevent the paper or cards from adhering to the roller or brush F.

Beneath the apron O is situated a secondary cleaning-brush, O, which serves to remove from said apron such particles of bronze that may adhere to, the same, and the bronze scraped off by this brush is received in a drawer, P, whence it can be returned to the bronze-reservoir J. I

My machine can be run independent of a printing-press; or, if desired, it may be connected with a printing-press, so that the cards or other articles after having passed through the printing-press are immediately and auto matically transferred to my machine.

2 LMPAWS A hood, R, covers the rollers D, E, F, and 2. The secondary cleaning-brush O in com- Qend prevents thebronzefrom being scattered bination with the endless carrying-apron (3, about and from being wasted. reservoir J, and rollers K, D, E, and F, sub- Whet I claim as new, and desire to secure stentially as set forth.
